Abstract

The saddle pads have a lower covering layer of a comfort fabric formed from a passive performance fiber. In use this layer lies against the back and sides of a horse and acts to wick perspiration from the horse. The perspiration is then absorbed by the cushioning layer which consists of a polymeric foam backing. The foam backing is, in turn, covered by another hydrophilic layer, which in one embodiment is synthetic sheepskin and in the other is a cloth cover. The saddle pads are constructed with a withers relief gusset.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to equine saddle pads, and more particularly to saddle pads having superior moisture-wicking capacity. The moisture-wicking capacity removes perspiration from the saddle area and enhances localized cooling of the horse.

2. Description of the Prior Art

A saddle pad is placed between the horse and the saddle and is traditionally structured from felt, cotton, wool, and sheepskin. More recently cushioning materials such as artificial sheepskin, polyurethane foams and other plastic foams of both open- and closed-cell configurations have been used.

Typically, in constructing saddle pads, extra care is taken to protect the withers and back of the horse from irritation from the weight and movement of the saddle and rider. The saddle pad also needs to enhance the stability of the saddle mounting so that slippage from the proper location on the horse's back is avoided.

In the disclosure which follows, significant attention is paid to the materials of construction and the teachings of prior art fibers have been considered. From 1970 to date E.I. du Pont de Nemours and Company, Wilmington, Del. through the DuPont Dacron Research Laboratory in North Carolina and the Central Research and Development in Delaware developed a family of passive performance fibers utilizing microfiber filaments. These materials are described briefly in the article entitled Viewpoint: 21^stCentury Fibers, International Fiber Journal (August, 1999-Vol. 14, Issue 4). The DuPont development of sculpted fibers variously described as oblong, four-channel and scalloped-oval, longitudinally grooved fibers are the subject, among others, of U.S. Pat. No. 3,914,488 to Gorrafa and U.S. Pat. Nos. 5,591,523, 5,626,961, 5,736,243 and, 6,013,368 to Aneja. The sculpted fibers (not round) led to the introduction of the COOLMAX® product group of fibers. Further background of this art is provided in U.S. Pat. No. 5,626,961, which background is incorporated herein by reference.

In the past, several saddle pad patents and published patent applications have come to the attention of the inventor hereof. These are:

SUMMARY

The disclosed invention provides a saddle pad, shown in two embodiments, each having a lower covering layer of a comfort fabric formed from a passive performance fiber. In use this layer lies against the back and sides of a horse and acts to wick perspiration from the horse. The perspiration is then absorbed by the cushioning layer which consists of a polymeric foam backing. The foam backing is, in turn, covered by another hydrophilic layer, which in one embodiment is synthetic sheepskin and in the other is a cloth cover. Details of construction are included below as is a description of a withers relief gusset.

DESCRIPTION OF PREFERRED EMBODIMENTS

For the purposes of this Description, the definitions of “passive performance fibers” and “comfort fabrics” are derived from the article in the International Fiber Journal and the DuPont patents cited hereinabove. A passive performance fiber is defined as a sculpted fiber, generally scalloped oval in cross section and having longitudinal grooves in the surface thereof which grooves create a mechanism for wicking away or transporting water from a body. A “comfort fabric” is defined as one utilizing a passive performance fiber and employed in an article that wicks perspiration away from a body.

In the first embodiment a moisture-wicking saddle pad is constructed entirely from synthetic materials. The structure is layered and provides optimal comfort for the horse by having a unique arrangement using recently developed comfort materials. In this embodiment, the pad is constructed with an upper shell which is peripherally attached to the lower shell assemblage and thus may be considered to be a self-binding pad.

Referring now to FIGS. 1 through 4 the saddle pad of the first embodiment is shown and is referred to generally by the reference designator 10. The upper shell 12 is a synthetic fleece body 14 mounted on a substrate or an open-weave backing material 16. Unlike natural fleece and, because there are no natural oils to wash off, synthetic fleece 14 retains its compressibility and memory after numerous washings. As noted in Leson, U.S. Pat. No. 6,421,989, supra, saddle pads constructed from natural materials such as raw wool, upon use, lose the natural oils during cleaning and have substantial changes in physical properties.

As best seen in the cross-sectional view FIG. 4, the perimeter or outer edge 18 is rolled to form a binding portion 20 that surrounds a lower shell 22. The lower shell 22 is an assemblage of a foam pad 24 and an outer cloth cover 26 fashioned from a fabric constructed of a microfiber filament—a passive performance fiber—described in greater detail hereinbelow. The foam pad 24, which acts to cushion the impact forces experienced during a ride, is a polymeric cushion foam. The cushion foam is either an open- or a closed-cell plastic foam selected from a cross-linked, low-density polyethylene; ethylene vinyl acetate (EVA); or, polyurethane. It is noted that such foams are most often admixtures of open and closed cells with the “open” and “closed” designation following the predominant cell structure.

In this embodiment, the foam pad 24 is attached to cover 26 by an hour glass quilting stitch 28 which is both decorative and functional. The all-over stitching 28 precludes the shifting or bunching up of the pad 24 relative to the cover 26. As mentioned previously the cover 26 is manufactured from a passive performance fiber under license from DuPont and is known as COOLMAX® fabric, a comfort fabric. The fiber is a sculpted fiber that when extruded is scalloped-oval in cross-section and has a plurality—four or more—of longitudinal channels. Products utilizing fabrics of these fibers are known for moisture-wicking superiority and special applications of the material continue to be found. Because the wicking characteristic is a function of the channeling of the fiber, the wicking does not change with fabric maintenance.

A nylon webbing or strap 30 is attached to the topside of saddle pad 10 and, when the pad is placed on the horse, the webbing follows the spine of the horse and bridges the two symmetrical sides of the saddle pad 10. Upon installation the forward portion of the strap 30 is constructed to be pulled upwards so that the area surrounding the withers of the horse is relieved.

Other nylon webbing or straps are mounted on the upper shell 12 to aid in the installation of the saddle pad 10 and saddle (not shown). These include girth straps 32 and 34 and

billet straps

36 and 38.

In use, the saddle pad 10 of the embodiment just described wicks the perspiration of the horse along the fiber channels of the COOLMAX® comfort fabric 26 and transports the perspiration through the foam pad 24 to the area of most highly hydrophilic material, namely, the synthetic fleece 14 of upper shell 12. Thus, after a ride when the saddle pad is demounted from the horse, the inner surface is dry and the outer surface is wet. Additionally, because synthetic materials are used, washing or hosing down the pads will not change the physical properties thereof.

Turning now to the second embodiment, another moisture-wicking saddle pad is shown which follows the same principles of construction as the above. In the drawing for this embodiment parts similar to those in the first embodiment are afforded reference designators “100” units higher. Thus, girth strap 132 is analogous to girth strap 32 of the first embodiment.

Referring now to FIGS. 5 through 8, the second embodiment is shown and is referred to generally by the reference designator 110. The upper shell or cover 112 is a plain fabric such as cotton or nylon and, as a portion of the pad extends, when installed, beyond the saddle, the color of the cover can be selected to match the silks of the owners. Further, in the embodiment as the upper shell 112 is a cloth cover, the binding is external double-roped binding 115.

As best seen in the cross-sectional view FIG. 8 the perimeter or outer edge 118 is attached by the double-roped binding 115 to a lower shell 122. Like the prior embodiment the lower shell 122 is an assemblage of a foam pad 124 and an outer cloth cover 126 of COOLMAX® fabric. Here, the COOLMAX® fabric is 65% polyester and 35% COOLMAX® pique. As this embodiment lacks the extremely hydrophilic fleece cover, the foam for cushioning, while selected from the same materials, is optimally more sponge-like and holds more of the perspiration wicked away by the COOLMAX® fabric.

The foam pad 124 is sandwiched between upper shell 112 and lower shell 122 by the hour-glass quilting stitch 128 which, in this embodiment, penetrates all three layers. The stitching performs the same function as described above.

In the second embodiment, the central bridge 130 terminates at the forward end 131 thereof in a withers relief gusset or insert 133. This structure relieves stress on the withers of the horse. Because of the use of a cloth cover 112, the withers relief means 133 is more prominent in this embodiment. The nylon webbing for girth straps 132 and 134 and for billet, straps 136 and 138 are analogous to those of the first embodiment.

In use, the saddle pad 110 of the second embodiment wicks the perspiration of the horse along the channeled, sculpted fibers to the sponge—like foam mass therebehind. The superior wicking of the lower shell 122 results, after use, in the surface thereof being dry. This has been found to minimize irritation from saddles and saddle pads.

It is understood that variations and modifications of the present invention may be made without departing from the spirit thereof. Further, the present invention is not limited by the embodiments disclosed, but only by the appended claims when read together with the foregoing specification.
